Description

【０００１】
【発明の属する技術分野】
本発明は、車体に連結する管を含む補強部材に合成樹脂製のインストルメントパネルを支持させる、自動車におけるインストルメントパネル支持構造に関する。
【０００２】
【従来の技術】
従来、自動車の衝突事故に起因して、乗員が頭部をインストルメントパネルの上面に衝突させたとき、車体の左右のフロントピラーに両端を連結されてインストルメントパネルを支持する補強部材がインストルメントパネルの変形を阻害して乗員の頭部に大なる衝撃力が加わることを回避するため、一般に、補強部材とインストルメントパネルとの間に、インストルメントパネルの十分な変形を許容する大なる緩衝空間を設けている（例えば、特開平９−２１０４号公報参照）。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記のように補強部材とインストルメントパネルとの間に大なる緩衝空間を設けることは、補強部材及びインストルメントパネルの近接配置ができないことを意味するもので、これが車室容積の拡張を妨げる一因となっている。
【０００４】
本発明は、かゝる事情に鑑みてなされたもので、補強部材及びインストルメントパネルの近接配置を可能にしながら、乗員の頭部がインストルメントパネルの上面に衝突した場合にはその衝撃力を効果的に吸収し得るようにして、乗員のダメージを極力少なくし得る、自動車におけるインストルメントパネル支持構造を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は、車体に連結する管を含む補強部材に合成樹脂製のインストルメントパネルを支持させる、自動車におけるインストルメントパネル支持構造において、前記補強部材の前記管の外周面をその全周に亘り包みながら該管と一体に結合され且つ発泡セルを有する合成樹脂発泡体製とされて、同質同重量の発泡させない合成樹脂を用いる場合よりも大きい断面係数が得られるようにした支持ボスと、下部エネルギ吸収部材要素とその下部エネルギ吸収部材要素の上面に接合される上部エネルギ吸収部材要素とで構成されて前記インストルメントパネルの裏面と前記補強部材の前記管との間に介在させた、発泡セルを有する合成樹脂発泡体製のエネルギ吸収部材とを備え、前記支持ボスは、前記下部エネルギ吸収部材要素と同一材料をもって一体に成形され、乗員の頭部が前記インストルメントパネルの上面に衝突したときに、該インストルメントパネルの変形もしくは破壊を伴いつゝ前記エネルギ吸収部材の発泡セルを破壊することによりその衝突エネルギを吸収するようにしたことを第１の特徴とし、また本発明は、車体に連結する管を含む補強部材に合成樹脂製のインストルメントパネルを支持させる、自動車におけるインストルメントパネル支持構造において、前記補強部材の前記管の外周面をその全周に亘り包みながら該管と一体に結合され且つ発泡セルを有する合成樹脂発泡体製とされて、同質同重量の発泡させない合成樹脂を用いる場合よりも大きい断面係数が得られるようにした支持ボスと、前記インストルメントパネルの裏面と補強部材の前記管との間に介在させた、発泡セルを有する合成樹脂発泡体製のエネルギ吸収部材とを備え、前記支持ボスは、前記エネルギ吸収部材と同一材料をもって一体に成形され、乗員の頭部が前記インストルメントパネルの上面に衝突したときに、該インストルメントパネルの変形もしくは破壊を伴いつゝ前記エネルギ吸収部材の発泡セルを破壊することによりその衝突エネルギを吸収するようにしたことを第２の特徴とする。
【０００６】
この第１、第２の各特徴によれば、乗員の頭部がインストルメントパネルの上面に衝突したときは、インストルメントパネルの変形もしくは破壊を伴いつゝエネルギ吸収部材の発泡セルを破壊することにより、衝撃エネルギを吸収することができる。これにより補強部材及びインストルメントパネルの近接配置を可能にしながら、乗員が受ける衝撃力を効果的に軽減することができる。しかもエネルギ吸収部材の発泡セルの大きさ、該部材の肉厚及び配置により吸収し得るエネルギの大きさを制御することができ、設計の自由度が大である。
【０００７】
また本発明は、上記特徴に加えて、前記エネルギ吸収部材を、空調用の箱形ダクトで構成したことを第３の特徴とする。この第３の特徴によれば、空調用の箱形ダクトがエネルギ吸収部材を兼用することにより、専用のエネルギ吸収部材を設ける必要がなく、構造の簡素化を図ることができる。
【０００８】
さらに本発明は、上記特徴に加えて、前記インストルメントパネルが乗員の頭部から衝撃力を集中して受けると予想される部位の裏側には、前記支持ボスの外周面から該部位に向かって起立する前記箱形ダクトの縦方向壁を配置したことを第４の特徴とする。この第４の特徴によれば、乗員の頭部がインストルメントパネルに与える衝撃力は箱形ダクトの縦方向壁に圧縮力として作用することになり、該縦方向壁は座屈破壊するまでに大なる衝撃エネルギを吸収することができる。この場合、該縦方向壁の肉厚や起立角度を選定することにより、吸収し得るエネルギの大きさを制御することができる。かくして補強部材及びインストルメントパネルの更なる近接配置を可能にしながら、乗員が受ける衝撃力を効果的に軽減することができる。
【０００９】
【発明の実施の形態】
本発明の実施の形態を、添付図面に示す本発明の実施例に基づいて以下に説明する。
【００１０】
図１は自動車の前部内装部品組立体の一要素であるステアリングハンガ部材（補強部材）の斜視図、図２は上記ステアリングハンガ部材を結合した空調用ダクト及びインストルメントパネルの分解斜視図、図３は上記ステアリングハンガ部材に結合した空調用ダクトの横断面図、図４はインストルメントパネルに乗員の頭部が衝突した場合の作用説明図である。
【００１１】
先ず図１及び図２において、符号Ａは自動車の前部内装部品組立体を示すもので、それは補強部材としてのステアリングハンガ部材１、空調用の箱形ダクト９及びインストルメントパネル１２を備えている。
【００１２】
ステアリングハンガ部材１は、鋼管からなる長軸ハンガビーム２と、その両端に溶接された左右一対のサイドブラケット４１ 、４２ と、左方のサイドブラケット４１ に一端を溶接されて長軸ハンガビーム２と平行に配置される短軸ハンガビーム３と、この短軸ハンガビーム３の他端を長軸ハンガビーム２の中間部に連結する左側中間ステー５１ と、それと対向するように長軸ハンガビーム２に結合される右側中間ステー５２ と、短軸ハンガビーム３の中間部を長軸ハンガビーム２に連結するコラム取付けブラケット６とからなっており、左右のサイドブラケット４１ 、４２ は車体の左右のフロントピラー（図示せず）にそれぞれボルト結合され、またコラム取付けブラケット６には、ステアリングハンドル２３を軸支するステアリングコラム２４が取付けられ、両中間ステー５１ 、５２ にはコンソールボックス取付けブラケット７が固着されるようになっている。
【００１３】
図２及び図３に示すように、空調用の箱形ダクト９は、合成樹脂発泡体製の下部ダクト要素１０と、その上面に接合される、同じく合成樹脂発泡体製の上部ダクト要素１１とで構成される。下部ダクト要素１０には、前記ステアリングハンガ部材１の長軸及び短軸ハンガビーム２、３の略全長にわたり、その外周面を包みながらそれと結合する支持ボス１０ａが同一材料をもって一体に成形される。
【００１４】
下部及び上部ダクト要素１０、１１を構成する合成樹脂発泡体は、相互に相溶性を有する。
【００１５】
インストルメントパネル１２は、上部ダクト要素１１と相溶性がある合成樹脂発泡体からなるパネル本体１３と、その表面に接合された、しぼ付きの合成樹脂表皮１４とで構成される。具体的には、全ての合成樹脂発泡体は、例えばオレフィン系のＰＰ（ポリプロピレン）を素材としている。そして下部ダクト要素１０と上部ダクト要素１１、上部ダクト要素１１とインストルメントパネル１２のパネル本体１３は、それぞれ超音波溶着される。
【００１６】
下部ダクト要素１０及び上部ダクト要素１１は、それらの間に左右方向に延びる第１通風路１５１ と、この第１通風路１５１ から車室側へ突出する三つの出口１７１ 、１７２ 、１７３ とを画成するもので、その第１通風路１５１ の中央部に開口する入口１６が下部ダクト要素１０に形成される。
【００１７】
また上部ダクト要素１１及びパネル本体１３は、それらの間に左右方向に延びる第２通風路１５２ 及び第３通風路１５３ を画成するものであり、上部ダクト要素１１には、第１通風路１５１ と第２通風路１５２ 、第１通風路１５１ と第３通風路１５３ の各間を連通する通孔２１、２２が設けられる。
【００１８】
インストルメントパネル１２には、前記三つの出口１７１ 、１７２ 、１７３ に連なる三つの正面吹き出し口１８１ 、１８２ 、１８３ と、第２通風路１５２ の両端に連通する左右一対の側方吹き出し口１９１ 、１９２ と、第３通風路１５３ からフロントウインドシールド（図示せず）の内面に向かって開口する複数の上面吹き出し口２０、２０…とが形成される。
【００１９】
而して、入口１６に、空調装置の送風ダクトを接続して、その空調装置を作動すれば、冷気又は暖気を入口１６から第１、第２及び第３通風路１５１ 、１５２ 、１５３ に流入させ、各吹き出し口１８１ 、１８２ 、１８３ ；１９１ 、１９２ ；２０、２０…から吹き出させることができる。
【００２０】
このような空調用の箱形ダクト９をエネルギ吸収部材に兼用するために、図３に明示するように、第１通風路１５１ の後壁となる縦方向壁９ａは、前記長軸ハンガビーム２の外周面に被着した支持ボス１０ａから起立して、自動車の衝突時、インストルメントパネル１２が乗員の頭部Ｈから衝撃力を集中して受けると予想される部位Ｐに向かうように配置される。そして、この縦方向壁９ａは、支持ボス１０ａに結合する根元に向かって肉厚を厚くするように形成される。
【００２１】
次に、この実施例の作用について説明する。
【００２２】
自動車が衝突事故に遭遇して過大な減速度を受けると、自動車の前席の乗員は前のめり姿勢となって頭部Ｈをインストルメントパネル１２の上面に衝突させることがある。乗員の頭部Ｈがインストルメントパネル１２の上面に衝突すると、図４に示すように、インストルメントパネル１２の変形もしくは破壊を伴いながら合成樹脂発泡体製の箱形ダクト９の縦方向壁９ａに圧縮荷重が加わり、その発泡セルを破壊し、全体が座屈するまでに大なる衝撃エネルギを吸収する。この場合、該縦方向壁９ａの発泡セルの大きさや肉厚、起立角度を選定することにより、吸収し得るエネルギの大きさを容易に制御することができる。特に、この実施例のように、縦方向壁９ａの肉厚を、支持ボス１０ａに結合する根元に向かって厚くすると、吸収エネルギの大きさが縦方向壁９ａの破壊の進行と共に増大することになり、縦方向壁９ａの限られた高さを衝撃エネルギの吸収に有効に利用することができる。
【００２３】
こうして、ステアリングハンガ部材１から起立する縦方向壁９ａの発泡セルの破壊により乗員が受ける衝撃力を効果的に軽減することができるので、ステアリングハンガ部材１及びインストルメントパネル１２の近接配置が可能となり、これらのレイアウトの自由度が増すと共に、車室容積の拡張を図ることができる。
【００２４】
しかも、空調用の箱形ダクト９がエネルギ吸収部材を兼用するので、専用のエネルギ吸収部材を設ける必要がなく、構造の簡素化をも図ることができる。
【００２５】
また、ステアリングハンガ部材１の長軸及び短軸ハンガビーム２、３の外周面には下部ダクト要素１０の支持ボス１０ａが成形され、その下部ダクト要素１０に上部ダクト要素１１が、上部ダクト要素１１にインストルメントパネル１２のパネル本体１３が順次溶着されるので、ねじ部材を使用することなく、もしくはその使用を大幅に少なくしながら、空調用ダクト９及びインストルメントパネル１２をステアリングハンガ部材１に支持することができる。したがって、前部内装部品組立体Ａの組立工数も大幅に減少することになり、そのコスト低減をもたらすことができる。
【００２６】
しかも、ステアリングハンガ部材１の長軸及び短軸ハンガビーム２、３に、その略全長にわたり下部ダクト要素１０の支持ボス１０ａが結合していることから、空調用ダクト９及びインストルメントパネル１２をステアリングハンガ部材１により効果的に補強することができると共に、ステアリングハンガ部材１も空調用ダクト９及びインストルメントパネル１２によって剛性を強化され、その結果、車体の左右のフロントピラー間の剛性及びステアリングコラム２４の支持剛性を効果的に高めることができる。
【００２７】
因みに、テストによれば、外径６０ｍｍ、肉厚１．６ｍｍの鋼管に、発泡倍率５、肉厚５ｍｍのＰＰ（ポリプロピレン）発泡体を被着した場合、そのような被着を施さない鋼管に比して、鋼管の剛性を１０％強化し得たことを確認している。
【００２８】
特に、支持ボス１０ａは、同質同重量の発泡させない合成樹脂に比して、大なる肉厚を得ることができるから、これを長軸及び短軸ハンガビーム２、３の外周面に被着した場合、支持ボス１０ａに大なる外径を与えて、その断面係数を大きく得ることができ、長軸及び短軸ハンガビーム２、３の剛性を効果的に強化することになる。
【００２９】
その上、支持ボス１０ａは、比重が鋼管より遙かに小さいから、長軸及び短軸ハンガビーム２、３を構成する鋼管の外径や肉厚を増加させた場合に比べて、支持ボス１０ａの被着による重量増は少ない。
【００３０】
また、インストルメントパネル１２は、そのパネル本体１３に溶着される上部ダクト要素１１との対向面間に上記第２及び第３通風路１５２ 、１５３ を画成するものであるから、上部ダクト要素１１と対をなす一方のダクト要素を兼ねることになり、複数の通風路を持つ空調用ダクトの構造の簡素化に寄与し得る。
【００３１】
さらに、インストルメントパネル１２のパネル本体１３、上部ダクト要素１１及び下部ダクト要素１０は相互に互いに相溶性がある合成樹脂発泡体で構成されるので、それらの溶着を簡単、確実に行うことができ、断熱性に優れた空調用ダクト９を安価に提供することができる。
【００３２】
以上の実施例は、エネルギ吸収部材としての箱形ダクト９が、支持ボス１０ａを一体に成形した下部ダクト要素１０（即ち下部エネルギ吸収部材要素）と、上部ダクト要素１１（即ち上部エネルギ吸収部材要素）とより構成されており、請求項１の発明に対応するものである。
【００３３】
本発明は上記実施例に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。
【００３４】
例えば、前記下部ダクト要素１０及び上部ダクト要素１１を一体成形することもでき、この場合の実施例は、請求項２の発明に対応する。また図示例の場合、縦方向壁９ａとインストルメントパネル１２の裏面との間に適当な間隙が設けられるが、その間隙をゼロとして、縦方向壁９ａをインストルメントパネル１２の裏面に当接させることもできる。
【００３５】
【発明の効果】
以上のように本発明の第１、第２の各特徴によれば、インストルメントパネルの裏面と補強部材の管との間に、発泡セルを有する合成樹脂発泡体製のエネルギ吸収部材を介在させて、乗員の頭部がインストルメントパネルの上面に衝突したとき、インストルメントパネルの変形もしくは破壊を伴いつゝエネルギ吸収部材の発泡セルを破壊することによりその衝突エネルギを吸収するようにしたので、補強部材及びインストルメントパネルの近接配置を可能にしながら、乗員が受ける衝撃力を効果的に軽減することができる。しかもエネルギ吸収部材の発泡セルの大きさ、該部材の肉厚及び配置により吸収し得るエネルギの大きさを制御することができ、設計の自由度が大である。
【００３６】
また特に補強部材の管の外周面をその全周に亘り包みながら該管と一体に結合される支持ボスが、上記エネルギ吸収部材と同一材料でもって一体成形されるので、該エネルギ吸収部材と同じく合成樹脂発泡体製となる上記支持ボスは、同質同重量の発泡させない合成樹脂を用いた場合に比して、大なる肉厚を得ることができて、支持ボスに大なる外径を与えて大きな断面係数を得ることができるから、補強部材の管の剛性を効果的に強化することができ、その上、この支持ボスは、比重が補強部材の管より小さいから、管の外径や肉厚を増加させた場合に比べて、支持ボスの被着による重量増は少なくてすむ。
【００３７】
また本発明の第３特徴によれば、エネルギ吸収部材を、空調用の箱形ダクトで構成したので、空調用の箱形ダクトがエネルギ吸収部材を兼用することにより、専用のエネルギ吸収部材を設ける必要がなく、構造の簡素化を図ることができる。
【００３８】
さらに本発明の第４の特徴によれば、インストルメントパネルが乗員の頭部から衝撃力を集中して受けると予想される部位の裏側には、上記支持ボスの外周面から該部位に向かって起立する前記箱形ダクトの縦方向壁を配置したので、乗員の頭部がインストルメントパネルに衝突したとき、その衝撃力が箱形ダクトの縦方向壁に圧縮力として作用することになり、該縦方向壁は発泡セルを破壊しながら座屈破壊するまでに大なる衝撃エネルギを吸収することができ、乗員が受ける衝撃力をより効果的に軽減することができる。しかも縦方向壁の肉厚や起立角度を選定することにより、吸収し得るエネルギの大きさを容易に制御することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an instrument panel support structure for an automobile, in which a reinforcing member including a pipe connected to a vehicle body supports an instrument panel made of synthetic resin.
[0002]
[Prior art]
Conventionally, when an occupant hits the head against the upper surface of an instrument panel due to an automobile collision accident, a reinforcing member supporting both ends of the vehicle body and supporting the instrument panel is connected to front left and right front pillars of the vehicle body. In general, a large buffer between the reinforcing member and the instrument panel is provided between the reinforcing member and the instrument panel to prevent a large impact force from being applied to the occupant's head by inhibiting the deformation of the panel. A space is provided (for example, see Japanese Patent Application Laid-Open No. 9-2104).
[0003]
[Problems to be solved by the invention]
However, providing a large buffer space between the reinforcing member and the instrument panel as described above means that the reinforcing member and the instrument panel cannot be arranged close to each other, and this increases the volume of the cabin. It is a factor that hinders.
[0004]
The present invention has been made in view of the above circumstances, and while enabling the reinforcement member and the instrument panel to be arranged close to each other, when the occupant's head collides with the upper surface of the instrument panel, the impact force is reduced. It is an object of the present invention to provide an instrument panel support structure for a motor vehicle capable of effectively absorbing and minimizing occupant damage.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an instrument panel support structure for an automobile, in which a reinforcing member including a pipe connected to a vehicle body supports an instrument panel made of a synthetic resin, an outer periphery of the pipe of the reinforcing member. It is made of a synthetic resin foam integrally formed with the tube while wrapping the surface around the entire circumference thereof, and is made of a synthetic resin foam having a foam cell so that a larger section modulus can be obtained than in the case of using a non-foamable synthetic resin of the same weight and the same weight. And a lower energy absorbing member element and an upper energy absorbing member element joined to the upper surface of the lower energy absorbing member element , between the back surface of the instrument panel and the pipe of the reinforcing member. is interposed, and a energy absorbing member made of a synthetic resin foam having a foam cell, the support boss, the lower energy absorption Are integrally molded with the timber elements of the same material, when the multiplication membered head collides with the upper surface of the instrument panel, destroy foam cells accompanied Oneゝthe energy absorbing member the deformation or destruction of the instrument panel The present invention has a first feature that the collision energy is absorbed by performing the above operation. Further, according to the present invention, there is provided an instrument for an automobile in which a reinforcing member including a pipe connected to a vehicle body supports an instrument panel made of synthetic resin. In the panel supporting structure, the reinforcing member is made of a synthetic resin foam integrally formed with the tube while wrapping the outer peripheral surface of the tube over the entire periphery thereof and having a foam cell, and is made of the same material and the same weight so as not to foam. a support boss which is adapted section modulus is obtained larger than the case of using the resin, reinforcing the rear surface of the instrument panel Is interposed between the tube timber, and a energy absorbing member made of a synthetic resin foam having a foam cell, the support boss is formed integrally with the energy absorbing member and the same material, multiply membered when the head collides with the upper surface of the instrument panel, that it has to absorb the collision energy by destroying the foam cells of the instrument panel One involves deformation or fracture ofゝthe energy absorbing member This is the second feature.
[0006]
According to the first and second features, when the occupant's head collides with the upper surface of the instrument panel, the foam cell of the energy absorbing member is destroyed with the deformation or destruction of the instrument panel. Thereby, impact energy can be absorbed. This makes it possible to effectively reduce the impact force applied to the occupant while enabling the reinforcing member and the instrument panel to be arranged close to each other. Moreover, the amount of energy that can be absorbed can be controlled by the size of the foam cells of the energy absorbing member, the thickness and the arrangement of the member, and the degree of freedom in design is large.
[0007]
Further, in the present invention, in addition to the above-described features, a third feature is that the energy absorbing member is formed of a box-shaped duct for air conditioning. According to the third feature, since the air-conditioning box-shaped duct also serves as the energy absorbing member, there is no need to provide a dedicated energy absorbing member, and the structure can be simplified.
[0008]
Further, in addition to the above-described features, the present invention further includes, on the back side of the portion where the instrument panel is expected to receive the impact force from the occupant's head in a concentrated manner, from the outer peripheral surface of the support boss toward the portion. A fourth feature is that a vertical wall of the upright box-shaped duct is arranged. According to the fourth feature, the impact force applied to the instrument panel by the occupant's head acts as a compressive force on the vertical wall of the box-shaped duct, and the vertical wall is buckled until it breaks. Large impact energy can be absorbed. In this case, the amount of energy that can be absorbed can be controlled by selecting the wall thickness and the upright angle of the vertical wall. Thus, the impact force received by the occupant can be effectively reduced while enabling the reinforcement member and the instrument panel to be arranged closer to each other.

[0014]
The synthetic resin foams forming the lower and upper duct elements 10, 11 are mutually compatible.
[0015]
The instrument panel 12 includes a panel main body 13 made of a synthetic resin foam compatible with the upper duct element 11, and a synthetic resin skin 14 with a grain bonded to the surface thereof. Specifically, all synthetic resin foams are made of, for example, olefin-based PP (polypropylene). Then, the lower duct element 10 and the upper duct element 11, and the upper duct element 11 and the panel body 13 of the instrument panel 12 are ultrasonically welded, respectively.
[0016]

[0017]
The upper duct element 11 and the panel body 13, which defines a second air flow passage 15 2 and the third air passage 15 3 extending in the lateral direction between them, the upper duct element 11, the first air road 15 1 and the second air passage 15 2, the first air passage 15 1 and the through hole 21, 22 communicating between each of the third ventilating passage 15 3 is provided.
[0018]
Installation The instrument panel 12, and the three outlets 17 1, 17 2, 17 three front outlet 18 1 connecting to 3, 18 2, 18 3, a pair of right and left communicating with the second air passage 15 2 at both ends a lateral outlet 19 1, 19 2, a plurality of top outlet 20, 20 ... which open toward the inner surface of the front windshield (not shown) is formed from the third ventilating passage 15 3.
[0019]
Thus, if the air duct of the air conditioner is connected to the inlet 16 and the air conditioner is operated, cool air or warm air is supplied from the inlet 16 to the first, second and third air passages 15 1 , 15 2 , 15. 3 and can be blown out from the outlets 18 1 , 18 2 , 18 3 ; 19 1 , 19 2 ;
[0020]
To also serves as a box-shaped duct 9 for such air conditioning to the energy absorbing member, as best shown in FIG. 3, the longitudinal wall 9a of the first air passage 15 1 in the rear wall, the long axis hanger beam 2 From the support boss 10a attached to the outer peripheral surface of the occupant, the instrument panel 12 is arranged so as to be directed to a portion P where it is expected to receive the impact force concentrated from the occupant's head H in the event of a vehicle collision. You. The vertical wall 9a is formed so as to increase in thickness toward the base connected to the support boss 10a.
[0021]
Next, the operation of this embodiment will be described.
[0022]
When the vehicle encounters a collision and receives excessive deceleration, the occupant in the front seat of the vehicle may be in a forward leaning posture and cause the head H to collide with the upper surface of the instrument panel 12. When the occupant's head H collides with the upper surface of the instrument panel 12, as shown in FIG. 4, the instrument panel 12 is deformed or destroyed while being attached to the vertical wall 9 a of the synthetic resin foam box-shaped duct 9. A compressive load is applied, which breaks the foam cells and absorbs a large amount of impact energy until the whole buckles. In this case, it is possible to easily control the amount of energy that can be absorbed by selecting the size, thickness, and standing angle of the foam cell of the vertical wall 9a. In particular, when the thickness of the vertical wall 9a is increased toward the base connected to the support boss 10a as in this embodiment, the magnitude of the absorbed energy increases as the breaking of the vertical wall 9a progresses. Thus, the limited height of the vertical wall 9a can be effectively used for absorbing impact energy.
[0023]
In this manner, the impact force applied to the occupant due to the destruction of the foam cells of the vertical wall 9a rising from the steering hanger member 1 can be effectively reduced, so that the steering hanger member 1 and the instrument panel 12 can be arranged close to each other. Thus, the degree of freedom of these layouts can be increased, and the capacity of the cabin can be expanded.
[0024]
Moreover, since the air-conditioning box-shaped duct 9 also serves as an energy absorbing member, there is no need to provide a dedicated energy absorbing member, and the structure can be simplified.
[0025]
A support boss 10a of the lower duct element 10 is formed on the outer peripheral surface of the long axis and short axis hanger beams 2 and 3 of the steering hanger member 1, and the upper duct element 11 and the upper duct element 11 are formed on the lower duct element 10. Since the panel main bodies 13 of the instrument panel 12 are sequentially welded, the air-conditioning duct 9 and the instrument panel 12 are supported on the steering hanger member 1 without using or greatly reducing the use of screw members. be able to. Therefore, the number of man-hours for assembling the front interior part assembly A is greatly reduced, and the cost can be reduced.
[0026]
Moreover, since the support boss 10a of the lower duct element 10 is connected to the long axis and short axis hanger beams 2, 3 of the steering hanger member 1 over substantially the entire length thereof, the air conditioning duct 9 and the instrument panel 12 are connected to the steering hanger. While the steering hanger member 1 can be effectively reinforced by the member 1, the rigidity of the steering hanger member 1 is also enhanced by the air conditioning duct 9 and the instrument panel 12, so that the rigidity between the left and right front pillars of the vehicle body and the steering column 24 The support rigidity can be effectively increased.
[0027]
Incidentally, according to the test, when a PP (polypropylene) foam having an expansion ratio of 5 and a thickness of 5 mm is applied to a steel pipe having an outer diameter of 60 mm and a thickness of 1.6 mm, the steel pipe is not subjected to such attachment. In comparison, it was confirmed that the rigidity of the steel pipe could be enhanced by 10%.
[0028]
In particular, since the supporting boss 10a can obtain a large wall thickness as compared with a synthetic resin of the same quality and the same weight which is not foamed, when the supporting boss 10a is attached to the outer peripheral surfaces of the long axis and short axis hanger beams 2 and 3, By providing a large outer diameter to the support boss 10a, it is possible to obtain a large section modulus, and the rigidity of the long axis and short axis hanger beams 2, 3 is effectively enhanced.
[0029]
In addition, since the specific gravity of the support boss 10a is much smaller than that of the steel tube, the support boss 10a has a larger specific diameter than the steel tube constituting the long and short axis hanger beams 2, 3. The weight increase due to the deposition is small.
[0030]
Further, the instrument panel 12, since it is intended to define the second and third ventilating passage 15 2, 15 3 between the facing surfaces of the upper duct element 11 which is welded to the panel body 13, an upper duct This also serves as one of the duct elements forming a pair with the element 11, which can contribute to simplification of the structure of the air conditioning duct having a plurality of ventilation paths.
[0031]
Furthermore, since the panel main body 13, the upper duct element 11, and the lower duct element 10 of the instrument panel 12 are made of mutually compatible synthetic resin foam, they can be easily and reliably welded. In addition, the air-conditioning duct 9 having excellent heat insulating properties can be provided at low cost.
[0032]
In the above-described embodiment, the box-shaped duct 9 as an energy absorbing member has a lower duct element 10 (that is, a lower energy absorbing member element) integrally formed with a support boss 10a and an upper duct element 11 (that is, an upper energy absorbing member element). ), And corresponds to the first aspect of the present invention.
[0033]
The present invention is not limited to the above embodiment, and various design changes can be made without departing from the gist of the present invention.
[0034]
For example, the lower duct element 10 and the upper duct element 11 can be integrally formed, and the embodiment in this case corresponds to the second aspect of the present invention. In the illustrated example, an appropriate gap is provided between the vertical wall 9a and the back surface of the instrument panel 12, but the gap is set to zero, and the vertical wall 9a is brought into contact with the back surface of the instrument panel 12. You can also.
[0035]
【The invention's effect】
As described above, according to the first and second features of the present invention, an energy absorbing member made of a synthetic resin foam having foam cells is interposed between the back surface of the instrument panel and the pipe of the reinforcing member. Therefore, when the occupant's head collides with the upper surface of the instrument panel, the foam cell of the energy absorbing member is destroyed with the deformation or destruction of the instrument panel, thereby absorbing the collision energy. The impact force received by the occupant can be effectively reduced while enabling the reinforcing member and the instrument panel to be arranged close to each other. Moreover, the amount of energy that can be absorbed can be controlled by the size of the foam cells of the energy absorbing member, the thickness and the arrangement of the member, and the degree of freedom in design is large.
[0036]
The support boss which is particularly coupled to the outer peripheral surface of the pipe of the reinforcement member to the tube integrally with wrapped over its entire circumference, since it is integrally molded with the same material as the energy absorbing member, and said energy absorbing member also synthetic resin foam made to become the support boss, as compared with the case of using the homogeneous same weight foamed was not a synthetic resin, and it is possible to obtain large becomes a thick, giving an outer diameter larger becomes the support boss since Ru can obtain a large section modulus Te, it is possible to enhance the rigidity of the tube of the reinforcing member effectively, thereon, the support boss, because the specific gravity is smaller than the tube of the reinforcing member, the outer diameter of the tube The increase in weight due to the attachment of the support boss can be smaller than when the thickness is increased.
[0037]
According to the third feature of the present invention, since the energy absorbing member is constituted by the air-conditioning box-shaped duct, the dedicated air-conditioning box-shaped duct also serves as the energy absorbing member, thereby providing a dedicated energy absorbing member. There is no need, and the structure can be simplified.
[0038]
Further, according to the fourth feature of the present invention, on the back side of the part where the instrument panel is expected to receive the impact force from the occupant's head in a concentrated manner, from the outer peripheral surface of the support boss toward the part. Since the vertical wall of the upright box-shaped duct is arranged, when the occupant's head collides with the instrument panel, the impact force acts on the vertical wall of the box-shaped duct as a compressive force. The vertical wall can absorb a large amount of impact energy before buckling while destroying the foam cell, and can more effectively reduce the impact force received by the occupant. Moreover, by selecting the wall thickness and the rising angle of the vertical wall, the amount of energy that can be absorbed can be easily controlled.
